The Canadian government should renew funding for a soon-to-end Arctic climate and atmospheric research program, a group of more than 250 international climate scientists is arguing in an open letter to Prime Minister Justin Trudeau. Read more in Science.
The Canadian High Arctic Research Station in Cambridge Bay will serve as a base for scientists studying everything from the region’s changing cryosphere to how to best deploy renewable energy projects in northern communities.
THIS OCTOBER, AS winter begins to draw near in the Canadian Arctic, a new research facility will finally open its doors.
The Canadian High Arctic Research Station (CHARS) in Cambridge Bay, Nunavut, has been 10 years in the making. First announced by the government in 2007, construction on the C$200 million (US$165 million) facility began in 2014 and should be completed by next year – but the official grand opening is set for October, to coincide with Canada’s 150th birthday year.

A health survey of Inuit communities in northern Quebec found widespread food insecurity and other problems 13 years ago. A follow-up now underway will see how much things have changed.
THE CCGS AMUNDSEN, Canada’s Arctic research icebreaker, has begun a unique portion of its summer research schedule – visiting 14 remote Inuit communities along the shore of Hudson Bay and the Hudson Strait in northern Quebec as part of a large-scale survey of the population’s health and well-being.

New research aims to better understand how much methane – a potent greenhouse gas – is burbling to the surface of the Mackenzie Valley in Canada’s Northwest Territories as the permafrost melts.
Hidden beneath the frozen ground of the Arctic could be a ticking time bomb. Vast reservoirs of methane – a greenhouse gas 30 times more potent than carbon dioxide – lie beneath the permafrost, and as global temperatures rise and the permafrost thaws, it could leak out and speed up the pace of climate change in an ever-faster vicious circle.
A team of researchers from Germany spent two years measuring the release of methane from the Mackenzie River Delta in northern Canada. They were trying to figure out how much of the gas was the normal “biogenic” emissions produced each summer by decomposing organic matter in Arctic wetlands, and how much is coming from ancient underground “geologic” sources leaking through gaps in the permafrost year-round.

CFI aims to secure ongoing operation and maintenance funds for research facilities including Canada’s only research icebreaker.
Laval University has received more than $18 million for the research icebreaker CCGS Amundsen in the latest round of funding from the Canada Foundation for Innovation’s Major Science Initiatives Fund.
Over the next five years, the funding will mainly be used to maintain and deploy the coast guard ship’s scientific equipment and to pay the specialised engineers who operate the Arctic research vessel, says Louis Fortier, the Amundsen’s scientific director. But the money will also be used to subsidize some scientific projects that need a little extra cash. Read more in University Affairs.
Mercury pollution in marine animals may be behind a population crash.
An isolated population of Arctic foxes that dines only on marine animals seems to be slowly succumbing to mercury poisoning.
The foxes on Mednyi Island — one of Russia’s Commander Islands in the Bering Sea — are a subspecies of Arctic fox (Vulpes lagopus) that may have remained isolated for thousands of years. They were once numerous enough to support a small yet thriving group of fur hunters. After humans abandoned the settlement in the 1970s, the fox population began to crash, falling from more than 1,000 animals to fewer than 100 individuals today. Read more in Nature.
